I bought a plexi plus kit from musikfìding, and my problem is that I have no sound in bypass and also when the circuit is on.
I had a problem with the 3pdt board infact I soldered the switch in the wrong side of the board, so I desoldered the switch and I wired the 3pdt without board. I tested the switch and it worked, i bias the j201 at 5V like the build docs.
Moreover when i power on the bi coloured led is red while I think it would be green.
Since you do not have signal in either bypass or effect, it indicates that you have not wired the footswitch/jacks and board correctly. Without using the 3PDT wiring board, use the first diagram in this guide to do the wiring:
